Abstract

The concentration of an element in a molten metallurgical phase (3) is measured by applying an electrical potential across two electrodes (1, 2) separated by a solid electrolyte (7) containing cations of the element to be measured immersed in the melt, and measuring the current flowing between them. The solid electrolyte is preferably of beta -alumina or zirconium silicate or phosphate.
